PCIe 5.0 SSDs – Most New Drives Depend on the Phison E26 Controller

“Most of the drives we’ve seen rely on the Phison PS5026-E26 (or E26 for short). This 12nm controller has 8 channels and promises up to 2400 MT/S with a theoretical maximum sequential read speed of 14,000 MBps and a sequential write speed of up to 11,800 MBps. None of the drives is rated for speeds quite that high.

The Phison E26 also boasts up to 1.5 million read IOPS and 2 million writer IOPS. To achieve maximum speeds, a drive would have to have ideal firmware and very fast NAND flash..”
